Poly Bags for Amazon FBA, DTC Brands & 3PL Warehouses
E-commerce fulfillment demands packaging that is fast to apply, cost-effective at volume, and compliant with marketplace requirements. Flexible Poly Industries supplies suffocation warning bags, poly mailers, resealable bags, and shipping supplies for online sellers, 3PL warehouses, and Amazon FBA operations. With nationwide shipping on stock items from our Los Angeles location, we help e-commerce businesses maintain their fulfillment pace without packaging delays.
Our bags meet Amazon FBA prep requirements out of the box — pre-printed trilingual suffocation warnings, correct mil thickness, and proper sizing. For DTC brands, we offer custom printed bags that turn your packaging into a branding opportunity. And for 3PL warehouses processing thousands of orders daily, we provide the reliability, consistency, and volume pricing that keeps operations running smoothly.
E-commerce packaging operates under specific marketplace requirements that vary by platform. Amazon FBA has the most detailed requirements: poly bags must be at least 1.5 mil thick, carry a suffocation warning if the opening exceeds 5 inches, be sealed (heat seal, tape, or self-seal), and be transparent enough for barcode scanning. Walmart Marketplace, Target Plus, and other platforms have their own packaging guidelines. Non-compliance results in rejected shipments, additional fees, and delayed listings — all of which cost money and damage seller metrics.
The DTC (direct-to-consumer) market has shifted packaging expectations significantly. Customers now evaluate brands partly on their unboxing experience, and a cheap, flimsy poly bag sends the wrong message about product quality. Branded resealable bags, custom printed poly bags, and tissue-lined packaging create moments of delight that drive repeat purchases and social media shares. We help DTC brands achieve premium packaging presentation without premium pricing by offering custom printing on the same high-quality LDPE bags used by major retail brands.
Third-party logistics providers (3PLs) and fulfillment centers need packaging supplies they can count on — consistent quality, reliable stock availability, and competitive bulk pricing. A 3PL that runs out of bags or receives inconsistent material shuts down packing lines and delays shipments for every client they serve. We maintain deep stock on popular e-commerce bag sizes and provide dedicated account support for 3PL operations that need consistent supply and priority fulfillment.
The Southern California e-commerce ecosystem is massive, with thousands of online sellers, FBA prep centers, and fulfillment warehouses concentrated in the Los Angeles, Inland Empire, and Orange County areas. Our Pasadena location puts us at the center of this market, enabling local delivery to local warehouses and fast ground shipping to operations throughout the western United States.

Common questions about poly bags and packaging for e-commerce & fulfillment packaging.
Amazon requires poly bags with suffocation warnings if the opening is 5 inches or larger, minimum 1.5 mil thickness, and the bag must be sealed (tape, heat seal, or self-seal). The suffocation warning must be printed on the bag or on a label affixed to it, in a readable font size. Our suffocation warning bags meet all these requirements out of the box — just insert your product and seal.
Yes. We offer volume discounts starting at 10+ cases, with significant savings at pallet quantities. The more you order, the lower the per-bag cost. We also offer recurring order programs for sellers with predictable monthly bag consumption. Contact us with your monthly volumes for a custom quote.
Yes. Custom printed poly bags with your logo turn every shipment into a branding moment. Available with up to 6-color flexographic printing on any bag style — lay flat, gusseted, or resealable. Most DTC brands print their logo, website URL, and social media handles. Custom branded bags typically cost only pennies more per bag than plain bags.
Match the bag to your product with 1-2 inches of clearance on each side for easy insertion. Common sizes: 9"x12" for most clothing items and small products, 12"x18" for larger products and folded sweaters, 14"x20" for bulky items and multi-packs. If you are unsure, order a size sample pack to test with your actual products before committing to volume.
Stock bags ship with competitive lead times on orders placed before the cutoff time. Ground delivery reaches most of California next day, and the rest of the western US within 2-3 days. For time-critical needs, expedited shipping is available. We also offer scheduled recurring shipments for fulfillment centers that need consistent weekly or monthly supply.
Yes. FBA prep centers are one of our primary customer segments. Our suffocation warning bags meet all current FBA requirements, ship in standard case packs for efficient warehouse storage, and are available in the full range of FBA sizes. Many prep centers in the LA and Inland Empire area use us as their primary bag supplier.
1.5 mil is the minimum thickness Amazon requires and works well for lightweight products like clothing, accessories, and soft goods. 2 mil provides additional puncture resistance and rigidity, making it better for heavier products, items with sharp edges, or products that will be handled roughly in the fulfillment process. The cost difference is modest — about 10-15% more per bag for the heavier gauge.
Yes. Custom printed bags can include both the required suffocation warning text and your brand logo, creating a compliant and branded packaging solution. This is increasingly popular with FBA sellers who also sell DTC and want consistent branded packaging across all channels. Minimum order quantities apply for custom printed bags.
